Wireless communications method, user equipment, base station and system

Abstract

Embodiments of the present disclosure provide a wireless communications method, user equipment, a base station and a system, and relate to the field of wireless communications. The method includes: acquiring a frequency domain spreading factor, a symbol-level spreading factor and a transmission time interval-level spreading factor; and performing frequency domain spreading, symbol-level spreading and transmission time interval-level spreading on first to-be-sent information respectively according to the acquired spreading factors and sending first spread information; or, despreading, according to the acquired spreading factors, second spread information sent by a base station.

What is claimed is: 
     
       1. A wireless communications method, comprising:
 acquiring a transmission time interval-level spreading factor; 
 determining an actual spreading factor and a replication factor according to the transmission time interval-level spreading factor, wherein the transmission time interval-level spreading factor is a product of the actual spreading factor and the replication factor; 
 performing transmission time interval-level spreading on first to-be-sent information according to the actual spreading factor, to obtain a first transmission time interval-level spreading information; 
 replicating the first transmission time interval-level spreading information according to the replication factor, to obtain spread information; and 
 transmitting the spread information. 
 
     
     
       2. The method according to  claim 1 , wherein the acquiring the transmission time interval-level spreading factor comprises:
 receiving the transmission time interval-level spreading factor that is sent by a base station. 
 
     
     
       3. The method according to  claim 1 , wherein the performing the transmission time interval-level spreading on the first to-be-sent information according to the actual spreading factor comprises:
 repeating the first to-be-sent information according to the actual spreading factor, wherein a number of repetitions equals to the actual spreading factor value, to obtain the first transmission time interval-level spreading information. 
 
     
     
       4. The method according to  claim 1 , wherein a number of replicating time equals to the replication factor value. 
     
     
       5. A wireless communications method, comprising:
 acquiring a transmission time interval-level spreading factor; 
 determining an actual spreading factor and a replication factor according to the transmission time interval-level spreading factor, wherein the transmission time interval-level spreading factor is a product of the actual spreading factor and the replication factor; and 
 receiving a first information according to the replication factor and the actual spreading factor, wherein the receiving the first information according to the replication factor and the actual spreading factor comprises: 
 receiving a spread information, and 
 determining the first information according to the replication factor, the actual spreading factor, and the spread information. 
 
     
     
       6. The method according to  claim 5 , wherein the acquiring the transmission time interval-level spreading factor comprises:
 receiving the transmission time interval-level spreading factor that is sent by a base station.
